Definitions
- the invention relates to transparent substrates, in particular glass, coated with a stack of thin layers comprising at least one layer of the metallic type which can act on solar radiation and / or on the infrared radiation of long wavelengths.
- a stack of thin layers comprising at least one layer of the metallic type which can act on solar radiation and / or on the infrared radiation of long wavelengths.
- the invention relates in particular to a system of low-emissivity layers, consisting of at least four layers, for transparent substrates, in particular in glass, with at least one functional silver layer, a dielectric anti-reflective base layer, an anti-reflective protective layer dielectric and a blocking layer disposed between the silver layer and the anti-reflective protective layer, consisting of a metal, a metal alloy or of a substoichiometric oxide of a metal or a metal alloy.
- Stacks of functional layers of this type are known as many embodiments.
- the purpose of the blocking layer is to protect the silver layer from diffusing oxygen, which would lead to an alteration of the silver layer, which, on the one hand, the emissivity of the layer system is increased and on the other hand, the appearance layer optics are adversely changed.
- EP-0 104 870 and EP-0 233 003 thus describe layers locking devices made of different metals, including aluminum.
- the EP-0 035 906 also describes the possibility that the layer blocking can also be silicon.
- the metals and alloys suitable for the blocking layer are those which have a high affinity for oxygen and which have a strong bond with oxygen.
- the activity of the blocking layer is of particular importance when the coated substrates are heat treated at elevated temperatures. This is, for example, the case when the coated glass substrates are heated to their softening temperature of approximately 650 ° C. in order to bend them to this temperature or subject them to pretension by marked cooling (heat treatment of the quenching type or annealed). It has been shown that the blocking layers known for this purpose are not yet sufficiently effective when they are deposited in very small thickness.
- the object of the invention is therefore to provide blocking layers with a particularly high oxygen binding activity, which have, already at a very small thickness, a high protective activity, so that the layers of layers have a high light transmission in the visible range, for example more than 70 and even more than 80%, with a lower emissivity, of the order of magnitude of at most 4%, especially 3% and less, and so that these stacks keep these properties after heat treatment at elevated temperatures.
- the subject of the invention is a transparent substrate, in particular glass, provided with a stack of at least four layers including at least one layer metallic functional with properties in the infrared type silver, a anti-reflective base layer of dielectric material, a protective layer anti-reflective dielectric material and a blocking layer disposed between the functional layer and the anti-reflective protective layer.
- This layer of blocking usually made of metal, metal alloy of substoichiometric oxide of one or more metals, comprises according to the invention a AlSi alloy.
- the “base” anti-reflective layers (under the functional layer considered) or “protective layer” (above) are either individual layers, i.e. an overlap of at least two layers of dielectric.
- the AlSi-based blocking layer can also be at least partially oxidized, and / or nitrided.
- the blocking layer is therefore based on an alloy AlSi.
- AlSi alloys are used with a composition in the range of 60 to 80% by weight of Al and 40 to 20% in Si weights, which may of course also contain small amounts other metals or impurities, which is often unavoidable in the preparation of such alloys.
- the layers of layers with a blocking layer according to the invention show remarkable stability, even during heat treatment at high temperature.
- This surprising effect can be explained by the fact that Al and Si form two different mixed oxides with strongly negative enthalpies of formation.
- Al 2 O 3 has a formation enthalpy of only -380 kcal / mole and SiO 2 , a formation enthalpy of only -203 kcal / mole
- the mixed oxide 3Al 2 O 3 -2SiO 2 has a enthalpy of formation of -1804 kcal / mole
- the mixed oxide Al 2 O 3 -SiO 2 an enthalpy of formation of -617 kcal / mole.
- the interstitial oxygen in the metal oxide layer being in particular part of the anti-reflective coating in protective dielectric, and which is in particular made of ZnO, is obviously fixed in a particularly strong manner, so that, during the subsequent heat treatment, the Ag layer is protected in a particularly effective manner with respect to the oxygen which diffuses, because this latter is maintained in the network by thermodynamically very stable mixed AI-Si oxides.
- the stack of layers comprises a layer based on ZnO disposed directly under the silver layer.
- this can contain an addition of Al and Si in the same quantity ratio as for the blocking layer.
- the structure of the silver layer is indeed favorably influenced when it is deposited on a layer based on ZnO. Its "doping" with Al and with Si has an additional effect in that, during a subsequent heat treatment, the silver layer on the side which makes facing the substrate, is also particularly well protected against the oxygen which diffuses, by the strong activity of fixation of Al and Si for oxygen: we thus have additional silver protection effects for each of the layers with which it is in contact.
- the ZnO: AlSi layer is obtained by spraying cathode reactive from a target containing metallic zinc, and in particular from 0.3 to 8% in Al and from 0.05 to 1% by weight of Si.
- the substrate coated in accordance with the invention comprises either a single functional layer of the silver type with its blocking layer comprising the AlSi alloy, ie at least two functional layers.
- At least one of the functional layers is provided with the blocking layer according to the invention, in particular at least the most away from the substrate.
- they are all provided with the layer blocking according to the invention.
- At least one of the antireflection layers of the stack is based on at least one of the following oxides: SnO 2 , ZnO, TiOL, In 2 O 3 , Bi 2 O 3 , ZrO 2 , Ta 2 O 5 , SiO 2 , Al 2 O 3 .
- At least one of the antireflection layers can also be based on at least one nitride of the Si 3 N 4 type , AIN, of an oxynitride of the SiON type or oxycarbide of the SiOC type.
- float glass plates 6 mm thick having the dimensions 6 x 3.2 m 2 , are covered by the cathode sputtering process by magnetic field.
- next layers Glass - SnO 2 20 nm - ZnO: Al 17 nm - Ag 11 nm - CrNi 8 nm - SnO 2 40 nm.
- the zinc target for the preparation of the ZnO: Al layer is sprayed by means of a reactive Ar / O 2 atmosphere, from a metallic Zn target, which is alloyed with 2% by weight of Al.
- samples 10 ⁇ 10 cm 2 in size are heated in a laboratory oven to 670 ° C. and subjected to a time-temperature cycle corresponding to the temperature cycle in a real oven. pretension (hardening).
- T L the light transmission
- E the emissivity
- R the electrical resistance
- the leaching behavior of Ag + from the layer before the heat treatment is determined, photometrically by means of the process called "Plattenmethode nach Kimmel et al.”, As described in the review “Glastechnische Berichte” 59 (1986) , pages 252 and following.
- the results of this process provide information on the structure of the silver layer; the thicker and more regular the atomic structure of the silver layer, the lower the possibility that silver ions will diffuse in the upper layers, in the presence of moisture and that the layer will be leached from it.
- a ZnO-based layer below the silver layer this possibility of diffusion is reduced, and the leaching behavior is improved.
- coated samples of size 60 x 80 cm 2 are heated in a conventional production oven to the pretension temperature and then pretended (quenched). These sample plates are evaluated visually.
- the plates samples processed in the production furnace also show a marked increase in emissivity.
- all samples have a colored veil after heat treatment. The results lead to the conclusion that the silver layer is altered by the oxygen which diffuses during heat treatment.
- float glass plates 6 mm thick of dimensions 6 ⁇ 3.2 m 2 , are provided with the following layer system: Glass - Si 3 N 4 10 nm - SnO 2 10 nm - ZnO: AlSi 17 nm - Ag 11 nm - AlSi 4 nm - SnO 2 40 nm.
- the AlSi blocking layer is sprayed in metallic form from a target which consists of 65.8% by weight of Al and 34.2% by weight of Si.
- the ZnO layer is sprayed in a working gas Ar / O 2 , reactively from a Zn target which contains 0.1% by weight of Si and 1.2% by weight of Al.
- the Si 3 N 4 layer is sprayed from a Si target with a double magnetron cathode in the medium frequency range with a reactive atmosphere Ar / N 2 .
- Laboratory samples have a shiny, flawless appearance, everything like the glass plates processed in the production system, also after heat treatment.
- the ratio of emissivity to electrical resistance is the same as for laboratory samples, the emissivity is 4% after heat treatment.
- the 6 mm thick float glass plates are provided with the following layer system: Glass - SnO 2 20 nm - ZnO: AlSi 17 nm - Ag 11 nm - AlSi 3 nm - Si 3 N 4 20 nm - SnO 2 20 nm.
